These challenges likely apply to educational psychology, though the field has been slow to address them. This article discusses current research norms, strategic solutions…

In systematic reviews, meta-analyses are routinely applied to summarize the results of the relevant studies for a specific research question. If one can assume that in all studies the same true effect is estimated, the application of a meta-analysis with common effect (commonly referred to as fixed-effect meta-analysis) is adequate. If…

Research synthesis of evaluation findings is a multistep process.

The process of estimating the average…

Historically, qualitative and quantitative approaches have been applied relatively separately in synthesizing qualitative and quantitative evidence, respectively, in several research domains. However, mixed methods approaches are becoming increasingly popular nowadays, and practices of combining qualitative and quantitative research components at…

Research on teacher ethics and the moral dimensions of teaching has contributed to extensive and valuable knowledge, which has sometimes led to constructive syntheses of positions. Four research problems which have been elucidated are discussed in this article: the relationship between care and justice, the conflict between the ethics of virtue…
